6.0L Power Stroke Engine and DrivetrainDiscussion of the 6.0L Power Stroke diesel engine and drivetrain in the 2003-Up Super Duties and Excursions.

I have a 04 F250 with the 6.0 in it. It is eating up the fuel and the truck will surge at times. The rpms will go up to 1000 or higher and stay that way. If i turn the truck off, it will go back to normal for a while. It is running a little rought. I took it to a shop and they plugged it in and said it had low fuel pressure, which can be dirty fuel filters, camshaft Position Sensor, Crankshaft Position Sensor, Injection pressure Sensor or the Map Sensor Hose. Didn't tell me very much, except alot of checking. I have changed the fuel filters. I see that the Camshaft position sensor is a little bit of work to get to on this engine. Where to start?
Every single Ford diesel I have owned has had the cam timing sensor go out ... but every time, it shut down and had to be towed. Doubt if this helps ... but that is my experience with cam timing sensors.
hmmmm to me it sounds like they are guessing. low fuel pressure would be either plugged filters or buggered pump from running with plugged filters for too long. i can't see how all the crap has anything to do with low F.P.
The 6.0 is not like the 7.3 that had a problematic CPS. The 6.0 uses two different sensors and it compares them so a "CPS problem" is very rare. I would take a run at what Bismic said. It sounds most logical and you can change the ICP yourself. It looks like a spark plug sticking out the center of the valve cover on the passenger side. Good luck let us know if it worked out for you.
I took my truck in and had them hook it up, it is the ICP sensor. That was the easy part, I buy the sensor and go home to put it on. That is the tricky part. For a 2004 F250 6.0 engine, the sensor can be in one of two places, which I did not know. The mechanic I went to and had the code reader hooked up told me the ICP sensor was where my EGR sensor was. So I take off the EGR sensor believing it is the ICP sensor, they look alike and have the same three wires coming out of them and same wire hook up, but different thread, the EGR has fine thread and the ICP have course threads. So back to the Ford store to check on the part and find out why they do not match. Ford gives me a 2004 sensor diagram for my truck, and I found out I pulled out the EGR sensor. Problem number 2, they give the diagram for the 2004 engine, not the 2003, so I am looking for an ICP sensor and it is not there. That is when I found out about the sticker on the valve cover. If you look on the passenger side valve cover you have a sticker that is either red or blue. Red means the engine is a 2003 engine and the sensor in under the turbo and some work to get to it. If the sticker is blue, you have a 2004 engine and the sensor is on the passenger valve cover area. I have the red sticker, so I could not get the part changed out yet. Thank you for all the information has been a lot of help.

Hmmm - I covered that in post #5, and so did RockDoctor.
Lots of posts around on on how to change out the ICP (2003) that is behind the turbo. I can post links to the instructions and I can even post pics.
